Since we follow IPC Class III, I've done experiments turning N2 on and off and measuring void level with both SnPb and SAC305 solder. In both cases there was a statistically significant, measurable increase in voids with N2, but it wasn't significant from a practical standpoint. In other words, other factors were much more important in voiding and if you control those then the contribution of N2 really doesn't matter.
